CVE-2024-53100

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> nvme: tcp: avoid race between queue_lock lock and destroy<br /> <br /> Commit 76d54bf20cdc ("nvme-tcp: don&amp;#39;t access released socket during<br /> error recovery") added a mutex_lock() call for the queue-&gt;queue_lock<br /> in nvme_tcp_get_address(). However, the mutex_lock() races with<br /> mutex_destroy() in nvme_tcp_free_queue(), and causes the WARN below.<br /> <br /> DEBUG_LOCKS_WARN_ON(lock-&gt;magic != lock)<br /> WARNING: CPU: 3 PID: 34077 at kernel/locking/mutex.c:587 __mutex_lock+0xcf0/0x1220<br /> Modules linked in: nvmet_tcp nvmet nvme_tcp nvme_fabrics iw_cm ib_cm ib_core pktcdvd nft_fib_inet nft_fib_ipv4 nft_fib_ipv6 nft_fib nft_reject_inet nf_reject_ipv4 nf_reject_ipv6 nft_reject nft_ct nft_chain_nat nf_nat nf_conntrack nf_defrag_ipv6 nf_defrag_ipv4 ip_set nf_tables qrtr sunrpc ppdev 9pnet_virtio 9pnet pcspkr netfs parport_pc parport e1000 i2c_piix4 i2c_smbus loop fuse nfnetlink zram bochs drm_vram_helper drm_ttm_helper ttm drm_kms_helper xfs drm sym53c8xx floppy nvme scsi_transport_spi nvme_core nvme_auth serio_raw ata_generic pata_acpi dm_multipath qemu_fw_cfg [last unloaded: ib_uverbs]<br /> CPU: 3 UID: 0 PID: 34077 Comm: udisksd Not tainted 6.11.0-rc7 #319<br /> Hardware name: QEMU Standard PC (i440FX + PIIX, 1996), BIOS 1.16.3-2.fc40 04/01/2014<br /> RIP: 0010:__mutex_lock+0xcf0/0x1220<br /> Code: 08 84 d2 0f 85 c8 04 00 00 8b 15 ef b6 c8 01 85 d2 0f 85 78 f4 ff ff 48 c7 c6 20 93 ee af 48 c7 c7 60 91 ee af e8 f0 a7 6d fd 0b e9 5e f4 ff ff 48 b8 00 00 00 00 00 fc ff df 4c 89 f2 48 c1<br /> RSP: 0018:ffff88811305f760 EFLAGS: 00010286<br /> RAX: 0000000000000000 RBX: ffff88812c652058 RCX: 0000000000000000<br /> RDX: 0000000000000000 RSI: 0000000000000004 RDI: 0000000000000001<br /> RBP: ffff88811305f8b0 R08: 0000000000000001 R09: ffffed1075c36341<br /> R10: ffff8883ae1b1a0b R11: 0000000000010498 R12: 0000000000000000<br /> R13: 0000000000000000 R14: dffffc0000000000 R15: ffff88812c652058<br /> FS: 00007f9713ae4980(0000) GS:ffff8883ae180000(0000) knlGS:0000000000000000<br /> CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033<br /> CR2: 00007fcd78483c7c CR3: 0000000122c38000 CR4: 00000000000006f0<br /> DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000<br /> DR3: 0000000000000000 DR6: 00000000fffe0ff0 DR7: 0000000000000400<br /> Call Trace:<br /> <br /> ? __warn.cold+0x5b/0x1af<br /> ? __mutex_lock+0xcf0/0x1220<br /> ? report_bug+0x1ec/0x390<br /> ? handle_bug+0x3c/0x80<br /> ? exc_invalid_op+0x13/0x40<br /> ? asm_exc_invalid_op+0x16/0x20<br /> ? __mutex_lock+0xcf0/0x1220<br /> ? nvme_tcp_get_address+0xc2/0x1e0 [nvme_tcp]<br /> ? __pfx___mutex_lock+0x10/0x10<br /> ? __lock_acquire+0xd6a/0x59e0<br /> ? nvme_tcp_get_address+0xc2/0x1e0 [nvme_tcp]<br /> nvme_tcp_get_address+0xc2/0x1e0 [nvme_tcp]<br /> ? __pfx_nvme_tcp_get_address+0x10/0x10 [nvme_tcp]<br /> nvme_sysfs_show_address+0x81/0xc0 [nvme_core]<br /> dev_attr_show+0x42/0x80<br /> ? __asan_memset+0x1f/0x40<br /> sysfs_kf_seq_show+0x1f0/0x370<br /> seq_read_iter+0x2cb/0x1130<br /> ? rw_verify_area+0x3b1/0x590<br /> ? __mutex_lock+0x433/0x1220<br /> vfs_read+0x6a6/0xa20<br /> ? lockdep_hardirqs_on+0x78/0x100<br /> ? __pfx_vfs_read+0x10/0x10<br /> ksys_read+0xf7/0x1d0<br /> ? __pfx_ksys_read+0x10/0x10<br /> ? __x64_sys_openat+0x105/0x1d0<br /> do_syscall_64+0x93/0x180<br /> ? lockdep_hardirqs_on_prepare+0x16d/0x400<br /> ? do_syscall_64+0x9f/0x180<br /> ? lockdep_hardirqs_on+0x78/0x100<br /> ? do_syscall_64+0x9f/0x180<br /> ? __pfx_ksys_read+0x10/0x10<br /> ? lockdep_hardirqs_on_prepare+0x16d/0x400<br /> ? do_syscall_64+0x9f/0x180<br /> ? lockdep_hardirqs_on+0x78/0x100<br /> ? do_syscall_64+0x9f/0x180<br /> ? lockdep_hardirqs_on_prepare+0x16d/0x400<br /> ? do_syscall_64+0x9f/0x180<br /> ? lockdep_hardirqs_on+0x78/0x100<br /> ? do_syscall_64+0x9f/0x180<br /> ? lockdep_hardirqs_on_prepare+0x16d/0x400<br /> ? do_syscall_64+0x9f/0x180<br /> ? lockdep_hardirqs_on+0x78/0x100<br /> ? do_syscall_64+0x9f/0x180<br /> ? lockdep_hardirqs_on_prepare+0x16d/0x400<br /> ? do_syscall_64+0x9f/0x180<br /> ? lockdep_hardirqs_on+0x78/0x100<br /> ? do_syscall_64+0x9f/0x180<br /> ? do_syscall_64+0x9f/0x180<br /> entry_SYSCALL_64_after_hwframe+0x76/0x7e<br /> RIP: 0033:0x7f9713f55cfa<br /> Code: 55 48 89 e5 48 83 ec 20 48 89 55 e8 48 89 75 f0 89 7d f8 e8 e8 74 f8 ff 48 8b 55 e8 48 8b 75 f0 4<br /> ---truncated---
